Dell Latitude 5491 Replacement Board

This genuine Dell OEM motherboard carries part number 61FGF and is built for the Latitude 5491 notebook. It arrives with an on-board Intel Core i5-8400H processor running at 2.5 GHz and integrated Intel graphics. The board serves as a direct replacement for units originally equipped with UMA graphics only.

Installation Notes for Technicians

Swapping this system board requires a full teardown of the Latitude 5491 chassis, so allocate adequate bench time and keep screw trays organised. The on-board CPU eliminates socket handling, but the dense connector layout leaves little room for error when re-seating display, keyboard and I/O flex cables. A common pitfall is ordering this UMA board for a discrete-graphics model; the two variants are not interchangeable and the wrong part will not post.

UMA Graphics Platform Constraints

Because the i5-8400H and its integrated graphics share the same package, the thermal solution must cool both the CPU cores and the GPU slice simultaneously. Sustained loads will hit the shared thermal ceiling faster than a discrete design, so expect throttling under prolonged heavy compute or video work. The board also lacks the extra power phases and video-output wiring needed for a dedicated GPU, ruling out any future graphics upgrade.

Questions sur cet article

How can I confirm the on-board i5-8400H is running at 2.5GHz after I install the 61FGF board?

Enter the system BIOS on first boot; the processor line should show Intel Core i5-8400H at 2.5GHz.

The listing says the board includes the i5-8400H — do I need to buy a separate CPU, cooler or thermal paste?

The processor is soldered to the board, so no separate CPU is required; reuse the original heatsink and apply fresh thermal paste.

My Latitude 5491 has integrated Intel graphics — is the 61FGF the correct version or do I need a different board?

The 61FGF is built for UMA graphics models only; it will not fit systems that shipped with discrete graphics.
